How do you find the distance between point A(-3, 5) and point B(4, -6) in the coordinate plane?
Having the points
We calculate the distance d with the formula:
So in this case we have:
You first work out the
In the horizontal (x) direction the distance is:
In the vertical (y) direction the distance is:
(you should draw this on coordinate paper)
We now have a right-sided triangle, where the hypotenuse is the distance between A and B.
Find distance between A (-3, 5) and B (4, -6)
Use formula for distance:
d = 13.04
